Integrated mechanization of coal mining is a significant increase in coal production, the only way to increase economic efficiency. In order to meet the growing demand for coal to be mass-produced mechanized mining equipment, the rapid increase in the integrated coal face mechanization. Therefore, the demand for hydraulic support is also increasing, while the hydraulic drive system is the heart of the work of the hydraulic support is an indispensable important component to the hydraulic support. The design of the main support for the cover of hydraulic mine support the design of the hydraulic system. Including the passage of jacks and jack column design, pump station design and the rational distribution of the overall design. Also involves a number of standard parts, such as the selection rules. At the same time, the performances of systematic loss, fever and efficiency are checked carefully. Key words: hydraulic transmission; hydraulic system; pump station; hydraulic support 目录
